Notes

I understand the “fix” introduces memory leaks. This may or may not matter.

no upstream patch available as of 2024-11-25. Terminals on Ubuntu shouldn’t allow executing arbitrary code because of escape sequences. This vulnerability only exists when busybox is built against musl instead of glibc, so marking as not-affected for Ubuntu.
